such as spindles for suspending and revolving the bowls of centrifugal'l separators, but it will be understood thatV it is not limited tosuch special use,Y

The improvementslof our inventioncomprise essentially a combination in which an elastic ange .coupling is interposed between the spindle and the lbearings through which such spindle is supported and revolved.

In4 the preferred form of our improvemerrtsas'it has been Vapplied heretofore, the verticalvshaft which carries and revolves the separator bowl extends freely through a stationary bearingwhich carries a prime mover through anti-friction bearings, the prime mover supporting and Vdriving the spindle through the iexible device.

The characteristic features of our improvements are fully set out'in the following description and the accompanying drawings in illustration thereof.

In the drawings, FigureV 1 illustrates a broken vertical sectional view of a centrifugal separator having a bowl suspended by a spindle to which our improvements are applied; Fig. 2'is an enlarged vertical see-V tional view of the improved bearing; Fig. 3 is a sectional view taken on the line 3X-3 of Fig. 2; Fig. 4 is a vertical 'sectional view in illustration of a modified form -of the bearing, Fig. 5 is a sectional view taken on the line 5*-5x of Fig.- 4, and Fig. 6 is a vertical sectional view of a further modification.

The invention as embodied bythe mechanism illustrated in Figs. 1, 2 and 3, comprises the support or frame 1 provided with the member 11 having screwed in its top the sleeve 2 through which passes freely the Specification of Letters Patent. Patented Dec. 27, 1921.

spindle 3 for suspending and revolving the bowl 4. v

Bearingv rings 5, provided withthe concentric external annular channels 51, are xed on the upwardly projectingtubular extension 21 of the sleeve 2; the upper part of the extension being reduced with the provision of a shoulder 211 on which the lower ring 5 bears, a spacingring 6 being sleeved on such part with the provision'of bearings for such rings, and a nut 7 being. screwed on the top of the extension into engagement with the upper ring 5 to hold the several rings in place.

A pulley 8, which has been placed on the extension 21 previously to the application thereto of the specilied rings,.contains the rings 9 provided with the internal circular races 91 concentric with the respective races 51, balls 10 being disposed in the complementary races of such rings 5 and 9. The rings 9 are fixed in a sleeve 11 which is disposed within the pulley 8, this sleeve having an internal bearing member 111 surrounding the ring 6, for spacing the rings 9 and hold-- ing them in place.

A recessed cap 12 having-an open top'is4 set in the top of the pulley 8 in close proximity to the top of the upper ring 9 and the sleeve 11, the nut 7 lying within the cap.

Thecap 12 is provided with the internal flange 121 and contains a felt ring 13 which rests on such flange, the ring being held in place by a stud 14 screwed radially through the cap and penetrating the ring. The spindle 3, which extends through the parts 121 and 13 within the cap 12, has a bearing ring 15 iixed on the top thereof by a screw 16, this ring being in free relation to the cap and having a stud 17 set therein and extending into the felt ring 13.

A duct 1211 extends through the cap 12 to supply a lubricant to the bearing members in the pulley 8, which has a well 81 in the bottom thereof for holding oil when the pulley 8 is at rest.

It will be understood that the weight of the bowl 41 is carried by the spindle 3 to the frame 1 through Jthe members described and that the revolution of the bowl through the 'application offorce as by the belt 18 on the pulley 8 transmits power through the elastic ring 13 which permits limited movement of the spindle and bowl laterally, angularly and longitudinally without the transmission 12 and the other end of the spring being connected by a stud 21 to the ring 15. In this form of the device, the spring neutralizesV the effects otherwise communicated to the anti-'friction bearings through the pulley.

In the form of the apparatus illustrated in Fig. 6the elastic ring or washer 131 is secured to the flange 121 of the cap 12 by thescrews 14:1 having their heads sunk belowthe top of the washer. The spindle `3 is connected to the washer frictionally by direct engagement therewith and by the ring 151 which engages the top of such washer, the ring being secured to the spindle by the screw 161 having the annular flange V161,1 sleeved on thespindle and engaging the ring in wedging relation. Here the frame member 11 is provided with the guardV 11L for the pulley 8.

Having described our invention, we claim:

1. The combination with a support and a vertical spindle, of mechanism comprising anti-friction `vbearings and elastic means whereby said spindle is suspended and revolved with relation to said support, said elastic means comprising a fibrous bearing member interposed between said bearings and spindle and adapted for modifying the effect on said bearings of irregular actions of said spindle.

2. rlhe combination with a support and a spindle, of mechanism whereby said spindle is suspended and revolved in relation to said support, said mechanism comprising a race ring carried by said support, a race ring means for connecting said second Vnamed raceV ring with said spindle, anti-friction devices engaged in the complementary races of the rings aforesaid, and driving means concentric with the race ring aforesaid, 45

comprising a pliable member through which power is transmitted to said spindle.

3. The combination of a frame, a sleeve detachably connected with said frame, a spindle revoluble in said sleeve, a ring having an exte lior circular race mounted on said sleeve, a ring having an interior circular race surrounding said ring first named, antifriction devices engaged in said races, and mechanism comprising elastic means adapted for connecting said second named ring with said spindle and driving means acting through said elastic means on said spindle.

et. The combination of a frame, a sleeve detachably connected with saidframe, af"

plurality of rings having external races fixed 'to said sleeve, a plurality of rings having DAVID rr. srninrmns.` GERALD D- GRosNnie.
